Application filed October a, 1910. Serial No. 585,163;

To ll l i may concern actuated toward the welt by a lever' which Be itknown that I, JOHN B; HADAWAY, a

of the illustrated embodiment of citizen of the United States, residingat Swampscott, in the county of Essex and State of Massachusetts, haveinvented certain- Improvements in Machines for Use in the Manufacture ofWelt-Shoes, of which the following description, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots.and shoes and particularly to a machine which is adapted for operationupon a shoe after the welt has been attached for the purpose of shapingthe welt and adjacent portions of the shoe.

It has been discovered that after the welt has been attached to the shoeby the inseam the welt may not only be beaten out to flatten it and beslit at certainportionsof the shoe to facilitate the flatteningoperation but it may also advantageously be; extended widthwise. I findthat it is practical to extend a welt in .the direction of its width asubstantial extent by properly pulling and rubbing it in the directionoutwardly away i from the shoe. I find that by the use of the presentinvention the welt itself and the inseam are actually improved and theshoe'is given a better'appearance by subjecting the shoe to thedescribed action. It has been proposed to substitute for the knife ofthe commercial welt beating and slashing machine, shown in my LettersPatent No. 875,171, a pair of grippinginembers which. were to bearranged between the hammer and the work support upon which the welt isrested as an anvil. These proposed gripping devices or clappers would.separatethe welt from the hammer and the anvil and prevent directengagement of the beating devices with the welt and it would beimpossible to employ with such an arrangement the welt slitting knifewhich is regarded as essential'to a practical machine.

In accordance with an important feature this present invention a weltbeating hammer directly engages the welt and has in addition to itsmovement in the direction to beat the welt a movement over the welt inpulling or rubbing contact with the Welt. Also in this embodiment of theinvention the hammer is pands to lighten the and more importanthas a'fixed fulcrum and to which the hammer 1s pivot-ally connected forswinging movement by means other than the lever while the hammer is incontact with the worl In. the construction shown, the hammer isconnected to the lever through a spring which. is compressed by the lastportion of the levers down-stroke and provides a dwell of the hammer uonthe work. Advantage is taken of this dwell to actuate the hammeroutwardly as the hammer pressure increases whereby to exert an outwardpull on the welt and to actuate the hammer farther outward in rubbingcontact with the welt as the lever rises and the spring exhammerpressure A further important feature of this invention is found in thecombination by which is made possible for the first time in one machinethe three functions of beating, extendlng or stretching and slitting thewelt in a single operation.

These and other features of this invention, including certaincombinations of parts features of construction will more fullyappear inconnection with the following description of the machine in which I havechosen to illustrate the invention for the purpose of explanation, andwill then be pointed out in the claims.

Figure l is a side elevation of a machine equipped with this invention.Fig. 2 is a section on line 22, Fig. 3. fragmentary view showing the thework at the end of a hammer stroke. Fig. 4 is a section on line-H ofFig. 2; Fig. 5 is a section on line 5-5 of Fig. 3. The'illustratedembodiment of theinvention comprises a welt beating hammer 1 having acavity 2 cut in its face to permit the access of the knife 20 to thewelt while under compression by the hammer. The hammer is mounteduponthe stem 3 carried by the hammer lever 6 of the machine. A spring 4received within the carrier of the hammer engages a shoulder onthehammer stem and normally operates to hold the hammer at the limit ofits downward movement determined by the adjustable stop collar 5 whichconsists of a' split nut secured upon the stem'3.

relation of The lever 6 is fulcrumed at 7 and has its rear end forked toembrace the block 10 of an eccentric 11 on the main shaft 12' of theFig. 3 is a 5 support is shaped to enter the welt crease of a weltedshoe and to support the welt as near as practicable to the inseam. Thewelt slitting knife 20 is supported by a carrier 21 which is mounted tobe reciprocated forwardly and backwardly in a guideway in a plate 24 bya lever 28 which carries a block confined in a slotted portion of thelever. The lever is fulcrumed at its lower end at 29 to the frame and itcarries a roll 30 which stands in thepath of a cam 32 rotated on a stubshaft 33 by a worm wheel 34 driven from a worm 35 on the main shaft 12.The cam is connected to the worm wheel by a clutch of the sliding boltvariety controlled v by a lever 49 pivoted at 50 and normally held by aspring 51 in position to hold the clutch open and the cam at rest. Atreadle 52 is provided to close the clutch connection and cause theknife to be driven in appropriate 2" time relation to the hammer when itis desired to slit the welt. The knife and its actuating mechanism mightbe omitted if not required.

The machine as thus far described is or may be substantially like thatshown in my prior Letters Patent No. 875,171 to which machine thepresent improvement is applied.

The hammer. with its stem 3 is mounted in a carrier 60 which is.pivotally connected with the lever 6 by trunnions 62 and said carrieralso has connection below said trunriions with the forward, nearlyhorizontal arm of a bell crank lever 65 the upwardly projecting arm ofwhich is connected by a rod 66 to the eccentric block 10 wherebyactuation of the bell crank 65 and of the hammer carrier 60 is eflectedin time rela tion to the beating movements of the hammer. Theseconnections move the hammer rearwardly or toward the outer edge of thewelt while the hammer is in engagement with the welt. More specificallystated, the eccentric has little effect on the bell crank during themajor part of the hammers 0 downward movement or until the eccentricblock starts backwardly whereupon it begins to move the bell crank inthe direction to draw the hammer over the welt toward the edge of thewelt first slowly and then more rapidly and continues to draw itrearwardly during the first half of the movement of the eccentric forraising the hammer carrying end of lever 6. The stop .collar 5 isusually adjusted so that .the hammer strikes the work a substantial timebefore the end of the down-stroke of its end of the lever 6 and thespring 4 yields toallow the lever to complete its stroke. This providesfor a dwell of substantial duration of the hammer upon the work duringthe last part of the downstroke of the lever 6 and the first portion ofits upstroke. It is during this period of engagement of the hammer withthe work that the bell crank effects backward swinging of the hammercarrier. The extent of this backward or swinging movement of the hammerhead is variable by an adjustable connect-ion between the bell crank 65and the link 64. The link and the connected arm of the bell crank formin effect a toggle which as it is broken begins slowly to pull thehammer carrier rearwardly over the welt and rapidly increases thisaction to the end of its breaking stroke. The bell crank arm has avertical slot in which the pivot pin connecting it to the link 6 1 isadjustable upwardly or downwardly with relation to the fulcrum .of thebell crank to initiate and carry on the movement of the hammer head moreor less rapidly. The effect of this backward movement of the hammercarrier is to rub the welt in the direction of its width and exert adrawing action which perceptibly extends the welt widthwise. Thisextension of the welt appears to be due to three causes: The welt isstraightened outwardly to overcome the effect of any contraction whichmay have occurred in the welt attaching operation, as for example, inbending the welt around the convex portions of the shoe edge; the weltis stretched widthwise more or less by the drawing effect of the hammeras it rubs over the welt under the pressure of the spring 4; and finallythe outward pull on'the welt seems to draw down upon the upstandinginner edge portion of the welt which is attached to the upstanding lipof the innersole. This last not only lets the welt pull outwardlyfarther but it also has a beneficial effect upon the inseam in that itdraws the seam down flatter and the upstanding portion of the welt seemsto exert a leverage tending to close the spaces between the welt, upperand lip in the trimmed face of the inseam.

By the use of this invention a narrower welt can be used in a shoe, andthe appearance of the shoe is improved both by getting a closer and aflatter inseam and by smoothing and firming the welt. Another practicaladvantage found in the use of this machine is that the action of thehammer in its crosswise movement with, and relatively to, the welt tendsto hold the shoe in the machine, thus materially assisting the operatorin his work by relieving him from considerable exertion in holding theshoe which he had to use in 'prior types of welt beating machines. Thehammer may advantageously be arranged to extend over the work beyond thework support and to engage the between-substance of the shoe on theupturned edge faces of the welt, upper, and innersole lip. By thisengagement these edge portions of the shoe stock are depressed to thelevel of the face of the welt so that the outersole may lie fiat uponthem and upon the welt. This beating action on the trimmed inseam or thebetween-substance is saved from being too severe by the fact that thelast, or the shoe as a Whole, is not rigidly supported but only the weltrests on the anvil as appears from the drawings. Also, the movement ofthe hammer laterally in contact with these faces assists in extendingthe Welt or tends to draw this portion of the shoe stock outwardly andto the outermost limit which any existing slackness will permit. 5 Theopening 2 in the hammer head through which the knife 20 works hasconverging side walls as appears from Fig. 5 in which the hammer isshown in section looking upwardly. As the ham-mer is moved outwardly incontact with the welt the edges of the converging walls rub upon thewelt and increase the width extending action of the hammer and also thetendency of the hammer to keep the shoe pressed toward the machine. Thehammer is rapidly driven so that as the welt'is fed along under itportions of the surface of the welt which are closely adjacent to eachother are subjected to this drawing action of the hammer face.
